    • A single pass ink jet printer includes a plurality of ink jet modules arranged in adjacent rows extending across the width of the surface of an object which is moved with respect to the printer. The modules are mounted on and joined to a manifold which is mounted in a support frame. Ink is supplied to the manifold through an opening in the frame and the manifold distributes the ink to corresponding openings in the ink jet modules where it is directed to arrays of ink pressure chambers and to an outlet which communicates with a corresponding return passage in the manifold leading back to the ink supply. As a result, ink is circulated continuously through all of the ink jet modules, thereby maintaining pigment in suspension in a pigmented ink. An ink supply is removably connected to the printhead through quick-disconnect couplings and, to prevent contamination of the ink in the printhead, filters are provided in the ink supply and at the inlet to the printhead. An additional filter, designed to trap only those particles which would block the orifices in the orifice plate, is positioned between the ink jet modules and the orifice plate.
    • 单通道喷墨打印机包括布置在相邻行中的多个喷墨模块,该喷墨模块延伸穿过相对于打印机移动的物体表面的宽度。 模块安装在并连接到安装在支撑框架中的歧管。 墨水通过框架中的开口供应到歧管,并且歧管将墨水分配到喷墨模块中的相应开口,其中它被引导到墨压力室的阵列以及与歧管中的相应返回通道连通的出口 导致墨水供应。 结果,油墨通过所有喷墨模块连续循环,从而将颜料悬浮在着色油墨中。 墨水供应通过快速断开的联接器可拆卸地连接到打印头,并且为了防止打印头中的墨水被污染,在墨水供应器和打印头的入口处提供过滤器。 设计成仅捕获那些阻挡孔板中的孔的颗粒的另外的过滤器位于喷墨模块和孔板之间。

    • In the ink jet printing system described in the specification, a hot melt ink jet printhead having two ink reservoirs is coupled through an ink supply line to a remote hot melt ink supply and a temperature controller is arranged to control the temperatures of the ink in the remote ink supply, the supply line, the ink reservoirs in the printhead and passages leading from the reservoirs to the ink jet orifices at selected temperature levels to inhibit high-temperature degradation of the ink while permitting the ink to be jetted at the desired jetting temperature. In addition, a pressure control system controls the pressure of the ink in the printhead at one or more selected levels to permit the printhead to be used at different orientations and to permit purging of air bubbles and contaminants from the orifice passageways and to supply a relatively high vacuum to a deaerator in the printhead to extract dissolved air from the ink. A check valve in the ink supply line permits the printhead to be positioned at different elevations with respect to the remote ink supply without causing any undesired flow of ink between the reservoir and the printhead.
    • 在本说明书中描述的喷墨打印系统中,具有两个墨水储存器的热熔喷墨打印头通过墨水供应管线连接到远程热熔体墨水供应源,并且设置温度控制器以控制墨水的温度 远程供墨,供应管线,打印头中的油墨储存器和从储存器引导到选定温度水平的喷墨孔的通道,以抑制油墨的高温劣化,同时允许油墨以所需的喷射温度喷射 。 此外,压力控制系统以一个或多个选定的水平来控制打印头中的墨水的压力,以允许打印头以不同的取向使用并且允许从孔口通道清洗气泡和污染物并提供相对的 打印头中的脱气器的高真空度以从油墨中提取溶解的空气。 墨水供应线中的止回阀允许打印头相对于远程墨水供应处于不同的高度,而不会在储存器和打印头之间引起不期望的墨水流动。
